SN75116N Equivalent & Substitute Parts

Part Overview

The SN75116N is a 1/1 Transceiver IC manufactured by Texas Instruments in a 16-DIP through-hole package. This component is classified as obsolete, indicating it is no longer in active production. Due to its obsolete status, sourcing original units may become increasingly difficult. Identifying compatible substitute parts ensures design continuity and supply chain reliability for applications requiring equivalent transceiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75116N is based on the following critical parameters:

• Functional Equivalence: Both parts must operate as 1/1 Transceiver ICs
• Electrical Compatibility: Supply voltage range must encompass or match the 4.5V ~ 5.5V requirement
• Regulatory Compliance: RoHS3 compliance ensures environmental and safety standards alignment
• Manufacturer Continuity: Texas Instruments as the original manufacturer provides design validation and technical support

The THVD1500DR qualifies as a substitute based on matching the 1/1 transceiver configuration, identical supply voltage range, and equivalent RoHS3 compliance status. However, differences in package type (surface mount vs. through hole), operating temperature range, and protocol specification must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The THVD1500DR is an active product from Texas Instruments with extended availability and ROHS3 compliance, making it suitable for new designs or redesigns requiring transceiver functionality. The shift from through-hole to surface-mount packaging and the reduction from 16-DIP to 8-SOIC requires PCB layout modification. The extended operating temperature range of the THVD1500DR (-40°C ~ 125°C) provides broader environmental tolerance compared to the SN75116N (0°C ~ 70°C), supporting applications in industrial or temperature-sensitive environments. Both parts maintain identical supply voltage specifications and equivalent regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the THVD1500DR directly replace the SN75116N without PCB modifications?

A: No. The THVD1500DR uses surface-mount 8-SOIC packaging, while the SN75116N uses through-hole 16-DIP packaging. PCB layout redesign is required for physical and electrical integration.

Q: Are the electrical specifications compatible between these parts?

A: Both parts share identical supply voltage requirements (4.5V ~ 5.5V) and equivalent 1/1 transceiver configuration. The THVD1500DR provides an extended operating temperature range, which is compatible with applications designed for the SN75116N's 0°C ~ 70°C specification.

Q: What is the significance of the product status difference?

A: The SN75116N is obsolete, meaning production has ceased and inventory is limited. The THVD1500DR is active, ensuring long-term availability and continued manufacturer support for technical documentation and supply chain reliability.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the SN75116N and THVD1500DR are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and safety requirements.

Q: What are the pin count differences?

A: The SN75116N is a 16-pin DIP package, while the THVD1500DR is an 8-pin SOIC package. Pin configuration differences require schematic and layout review before substitution.
